Application led September 1, 1900. Serial No. 28H87. (No model.)

To @ZZ 1071/0772/ it may concern.:

Be it known that l, PAUL F.. VIRT, a citizen of the United States, residing at Bloomsburg, in the county of Columbia and State of Pennsylvania, have invented a new and use ful Fountain-Pen, of which the following is a specification.

This invention relates to fountain-pens, particularly of the type in which the ink is fed to the pen principally by capillary attraction, and has special reference to certain improvements in the ink-feeding means and the cap to insure a positive sealing or cutting off of the flow of ink when the pen is not in use and the cap is placed thereover. To this end the invention primarily has in view the provision of novel ink-feeding means which shall be reliable and positive in action to provide for the proper graduated iow of ink to the pen, principally by capillary attraction, while at the same time so constructed as to coperate with a specially-constructed cap, whereby the cap when iitted over the pen will not only serve to cutoff the ilow or leakage of ink into the interior thereof, but will also provide for cutting off the direct flow of ink to the pen itself, thus keeping the penpoint clean and free from ink when the pen is not in use, besides permitting of perfect freedom in carrying or handling the pen in any position without possibility of the ink leaking into the cap or off from the pen, thereby soiling the clothing and lingers in the handling of the pen.

lVith these and many other objects in view, which will more readily appear to those familiar with the art as the nature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinafter described, illustrated, and claimed.

The essential feature of the invention, involving the directly-coperating elements of the cap and the ink-feeding device to provide for cut-ting olf or sealing the flow of ink into the cap and also to the pen-point, is necessarily susceptible of being embodied in a variety of modifications without departing from the spirit or scope of the invention; but for illustrative purposes there are shown in the drawings several preferred forms or embodiments of the invention.

In the drawings, Figure lis a longitudinal sectional View of a fountain-pen embodying' one form of the invention and showing the pen-cap fitted over the pen to provide for entirely cutting off the outward liow of the ink, either into the interior of the cap or to the penpoiut.

Fig. l0 is a longitudinal sectional view of the pen, showing another modification, illustrating means adapted for use in connection with a pen of the top-feed type, in which the feeding-finger, directly associated with the pen-point, lies upon the outer side thereof instead of upon the inner side, as shown in the other forms of the invention. Fig. 1l is a view similar to Fig. l0, showing a different position of parts from what is illustrated in said figure. Fig. 12 is a detail in perspective of the pen adapted for use with the construction shown in Figs. 10 and ll. Fig. 13 is a sectional View of the nozzle end portion of the pen, showing a modification in which the ink-feeding device maybe utilized as a fixed orstationary feeder when associated with an ordinary pen-cap.

Like n umerals of reference designate correspending parts in the several figures of the drawings.

'In carrying out the present invention the IOD general object in View is to provide an inkfeeding device having a movable element, in combination with the pen-cap, having a cutoff projection directly coperating with said movable element of the ink-feeding device to insure an effective sealingnf all passages andV fissures at the pen-bearing end of the holder, so as to effectually cut off the flow of ink not only to the pen, but also to the interior of the meral 1 designates the reservoir holder or barrel', which vmay be of any approved form; but in the present invention there is associated with said reservoir holder or barrel 1, which constitutes the main reservoirlfor the supply of ink, a tubular pen-cap 2, which is of the usual configuration, but which for the purposes of the presentinvention is provided with an interior eutro projection 3, which is preferably in the form of an elongated post or nipple disposed longitudinally of the cap and projecting from vthe inner side of its closed end toward the open end thereof. The precise configuration, length, and, in fact, arrangement of the, interior cut-off projection V3 of thepen-cap may be changed to suit they l particular type of ink-feeding device with which the same cooperates; but in those constructions which have been found best adapted for carrying out the invention the interior. cult-off projection-S of the cap is disposed not only longitudinally thereof, but centrally of the same, and is of a materially narrower widthy than the interior diameter of the bore.

ofthecapto leave an intervening annular pen-space LL, surrounding the projection or post 3 .and adapted to freely receive therein the pen or pen-point when the cap is fitted in place. In the construction illustrated in Fig. 1 of the drawingsthe interior longitudinallydisposed cut-olf post or nipple 3 is materially shorter than the length ofv the 'cap and is preferably provided with a rounded tip A5, which is designed to constitute a closure for the port, vent, or opening at the extreme outer end, of the ink-feeding device, as will be hereinafter presently explained.

Any suitable expedient may be resorted to forS effecting the connection between the cap and the reservoir holder or barrel, but a practical; construction is shown in the drawings all@ Consists in providing the cap at the open end thereof with interior threads 6, adapted to adjnstably engage with the extc rior-threaded collar or annulus 7 of the nozzle 8, which may be fitted to one end of the holder or barrel by any suitable joint connection-such,

vtain-pens. terior surface of the pen-bearing section 11 vto form the pen-seat12 the heel end of the for instance, as the screw-joint 10, illustrated in the, drawings.

To provide for the proper support of the elements of the ink-feeding device which are associated with the pen and also with the cap, the tubular nozzle 7, carried at one end of the holder or barrel, is coun-terbored to snugly receive within the outer end portion thereof the pen-bearing section 11, which is preferably in the form of a tubular plug and provides a passage for the ink, as well as for the admission of air, which is necessary to replace the ink, and thus insure the proper circulation or downward fiow of the ink during the operation of the pen. The said tubular pen-bearing section 11 is provided contigue ous to the outer end thereof with an exterior pen-seat 12, channeled in the periphery thereof and adapted tol receive the heel end of the pen or pen-point 13, which is of the usual form and preferably of gold, such as ordinarily employed in the best types of foun-A By reason of channeling the eX- pen will be firmly held in place in its interposed position between the exterior surface of the section 11 and the inner wall of the tu- `bular nozzle 8, and in addition to the pen- ;seat contiguous to the outer end thereofthe tubular pen-bearing section 11, which tightly fits within the nozzle, is provided at the in ner end thereof with a longitudinally-disposed rejtaining-notch 14, which cooperates with the ink-feeding device in the manner hereinafter 'f explained.

The ink-feeding device, whichcoperates with the interior cnt-off projection 3 of the pen-cap, may be made in a great variety of ways, so long as means are provided for a copious and positive flow of the ink to the Epen-point; but in the form of the invention s now being described and Shown in Figs. 1 to 7, inclusive, of the drawings the ink-feeding device essentially consists in its entirety of what might be properly termed a plungerfeeder 15. (Shown in detail in Figs. 4 and 5 of the drawings.) This plunger-feeder isarranged to extend loosely and longitudinally through the adjoining bores of the nozzle and the pen-bearing section 11, besides having elements coperating directly with the penpoint 18 and extending Within the holder or barrel 1 to insure the iiowing out of the ink. This plunger-feeder 15 essentially consists of a. semicylindrical shank 16, cut away longitudinally at one side, as at 17, nearly the entire length thereof to provide the necessary passages or channels, which establish and maintain communication between the interior of the holder or barrel and the interior of the pen-bearing section, with which also communicate the fissures, channels, or ways which serve to attract the ink by capillary attraction to the pen-point. The said semicylindrical shank 16 slidably fits Within the tubular pen-bearing section 11 and is pro- IIO vided at the outer end thereof with a feedhead 18, which head is provided at its inner side with an annular fissure-wall 19, which normally lies directly opposite and is arranged to be closed directly against the outer end of the pen-bearing section. At its outer side the terminal feed-head 18 of the plungerfeeder has extended therefrom a narrow tapering feed bar or finger 20, which underlies the pen-point 13 and serves to attract the ink downward from the fissure at one side of the wall 19 of the feed-head 18 when the pen is open and ready for use. The said terminal feed-head 18 is centrally bored to provide therein a longitudinally-disposed airvent 21, which communicates with the interior ofthe pen-bearing section and serves to provide direct communication between the outer air and the interior of the reservoir holder or barrel to permit of the necessary circulation of the ink, largely under capillary attraction from the reservoir to the pen-point. The outer exposed end of the air-vent 21 is concaved to form a seat 22 to receive the rounded tip 5 of the cut-of`f projection 8 when the cap is fitted to the nozzle of the pen.

At the inner side of its terminal feed-head 18 the semicylindrical shank 16 of the plunger-feeder is provided with a collar portion 28, upon which is arranged a non-corrosive retractile ad j usting-spring 24, which also fits within the spring-receiving socket 25, counterbored in the outer end portion of the penbearing section 11, so that one end of said spring bears against the shoulder provided by the annular fissure-wall 19 at the inner side of the feed -head 18. The tension of said retractile spring is normally exerted in a direction to provide for holding the shoulder or wall 19 of the terminal head 18 spaced a sufficient distance fromthe contiguous end of the pen-bearing section to provide an inkssure directly beneath the pen-point and which will be in communication with the necessary fissure or space provided between the pen-point and the underlying feed bar or iinger 2O at the outer end of the ink-feeding del vice.

The shank 1G of the plunger-feeder is provided at its extreme inner end with a retaining-head 2G, which is intersected by a holdinggroove 27, formed in the cut-off side of the shank and extendinglongitudinally thereof from the extreme inner end to the point where the terminal feed-head 18 is provided. The said holding-groove 27 is designed to receive therein one edge of a iiat supplemental feed bar or shaft 28. The fiat feed bar or shaft 28 fits within the groove 27 throughout the entire length of the latter, and the said bar is provided at one end with a narrow tapering iinger extension 29, which lies in the base of the groove 27 and extends well into the air-vent opening 21 through the outer head 18 of the plunger-feeder, thus insuring the conducting of the ink to a point where it will be freely drawn or flowed to the penpoint.

By reason of providing the flat supplemental feed bar or shaft 28 with the finger extension 29 the said bar or shaft is formed at an intermediate portion with an engaging shoulder 30, which loosely interlocks with the re-` taining-notch 14 in the inner end of the penbearing section 11, which interlocking engagement positively prevents a rotary or turning movementof the plunger-feeder, and consequently holds the same in permanent operative relation to the pen-point. It may be further observed at this point that the retaining-` notch 14 of the pen-bearing section is of such a depth as to positively gage or determine the separation of the shoulder or wall 19 of the feed-head from the contiguous end of the penbearing section, and thereby defines the extent of the ink-feeding fissure at thispoint. In other words, the engaging shoulder 30 of the supplemental feed bar or shaft 28 acts in the capacity of' a stop to arrest the outward movement of the plunger-feeder under the in- Iiuence of the retractile adj listing-spring when the pen-cap is removed.

In the'construction just described when the pen-cap 2 is removed the retractile adjustingspring 21 moves the plunger-feeder 15 outward, and thereby opens up the annular inkflowing fissure between the inner side of the feed-head 18 and the contiguous end of the pen-bearing section,thus maintaining au open channel for the free iiowing of the ink when the cap is off; but after using the pen when the cap is to be replaced the latter is screwed upon the nozzle 8, thus carrying the interior cut-off projection or post 3 thereof into registering contact with the seat at the outer end of the air-vent 21, thus eifectually closing this opening and cutting off leakage of ink therethrough. By a continued screwing of the cap in place upon the nozzle the plunger-feeder 15 is carried inward against the tension of the retractle adjusting-spring 24, thus moving the inner side or wall 19 of the terminal feed-head 18 against the contiguous end of the pen -bearing section and consequently closing the ink-iiowing fissure at this point. Means are therefore provided for carrying out the dual purpose of the invention-thatis, to close the openings or ports at the pen-bearing end of the holder when the cap is :replaced, thus permitting of the free handling of the pen in any position without danger of soiling the clothing or iingers.

Vith reference to the structural formation of the form of pen just described it may be explained that that part of the ink-feeding device underlying the pen-namely,the tapering feeding bar or finger 20-is designed to cause the feeding of the ink to the pen-point by the usual capillary action, and to secure this result capillary fissures or spaces may be provided between the pen and said underlying bar or finger by grooving the said bar or IIO finger or adjusting the upper surface thereof the proper distance from the pen to secure the necessary capillary space; but any of these orI other expedients known to the art maybe resorted to to provide sufcient attraction for the free flowing of the ink to the point of the pen.

The ink-feeding device constitutes such an important part of the pen that great care must be exercised in the construction of the different parts thereof to provide eicient attractive surface fissures, openings, or vents in order that the proper graduated circulation or downward flowing of the ink is preserved and at the same time ingress of air provided for in order that the pen maybe operated freely and with certainty at 'all times without dropping or skipping, which are serious defects in many forms of lfountain-pens now upon the market. In the form of ink-feeding device described the comparatively long plunger-feeder l5, in connection with the supplemental feed bar or shaft 28,

`serve vto attract and keep the general body of ink well down within the nozzlefor peni bearing section, so as to be taken readily to the pen by the feeding bar or linger-20, while the terminal feed-head 1S, with they properlygraduated air-Vent 21 and the annular inkowing fissure at one side thereof, serve to prevent the ink from running out precipitately from the lower end of the pen. Providing said supplemental feed bar or shaft with the narrow tapering finger extension 29 and having this extension projecting into the air-vent 2l, but not filling said Vent, serves to better -insure the keeping of the body of ink well down withinthe pen bearing section, and therefore means are provided in the present construction to maintain a copious iiow of ink through the inkflowing fissure about the feed-head 18. It is a recognized necessity in fountain-pen Vstructures to have a copious body of ink as near as possible to the point where it is to be taken by the feeder to the pen-point, besides insuring the proper entrance of air in the same zone, as such an arrangement secures the most sensitive supply to the pen. These conditions are supplied bythe construction of ink-feeding device alreadydescribed, and it may be further explained at this point that an additional function of the supplemental feed bar or shaft 28 is to assist in the attraction or drawing back of the ink within the reservoir when the pen is inverted and it is desired to replace the cap over the nozzle.

Various modifications of the construction already described may be resorted to and precisely the same result secured, and while the provision of the plunger-feeder and the supplemental feed bar or shaft, as herein set forth, secures the advantages ascribed to it, still it has been found thoroughly practical to carry out the invent-ion with the longitudinally-movable plunger-feeder having no auxiliary or supplemental feed bar or shaft.

Such a modification embodies the invention in one of its simplest and most practical aspects and is represented in Figs. 8 and 9 of the drawings. Referring particularly to these figures of the drawings, it will be noted that a plain longitudinal plunger-feeder 15a is employed, said feeder essentially consisting of a shank 31, extending into the reservoir and provided with an intermediate fiattened portion 32, lying within the pen-bearing section. The said shank of the plungerfeeder 15 is also provided at its outer end with a terminal feed-head 18a, similar to the one already described, and having extended outwardly therefrom the feeding bar or finger Y interior of the pen-bearing section through the said vent 21a, the intermediate flattened portion 32 of the plunger-shank 31 is provided contiguous to the head'ltav with a longitudinally-disposed air port or' slot 33, which is in direct communication with the said vent 21a.

The other change involving the modification shown in Figs. 8 and 9 over the construction already described and shown in Figs. 1 to 7, inclusive, is to provide the nozzle at its inner end with a retainingnotch 14, adapted to loosely receive therein an engaging lug 30a, which serves to prevent the plunger-feeder from turning within the pen-bearing section and also limits the outward movement thereof under the influence of the adjusting-spring to properly define the extent of the ink-flowing fissure between the inner side of the terminal feed-head and the contiguous end of the pen-bearing section. Inother respects the construction and operation'of the parts are substantially the same as previously set forth.

AIt is obvious that in the carrying out of the invention the improvements can be associated with pens of the top-feed type, as well as with those of the type in which the feeding bar or finger underlies the pen-point, and in Figs. 10, 11, and 12-of the drawings is shown a modification involving a construction which admits of the feeding of the ink onto the upper side of the pen-point. In the modication shown in Figs. 10, l1, and 12 of the drawings the construction and operation of the plunger-feeder are precisely the same as the construction and operation of the plungerfeeder illustrated in Figs. 8 and 9 of the drawings, with the single exception of omitting the feeding bar or nger 2Oa from the termi-- IOO ing section and the interior of the capillary space or channel between the feeding bar or finger 2Ob and the upper or outer side of the pen-point the latter is provided therein with an ink-port 34. When the plunger-feeder is in its normal extended position to provide the ink-flowing fissure between the terminal feed-head 1S and the contiguous end of the pen-bearing section, the said ink-port 34 in the point is uncovered and placed directly in communication with said inkiiowing fissure; but upon replacing the cap over the pen the terminal feed-head 1S of the plunger-feeder is closed against the contiguous end of the pen-bearing section, thus closing the inkflowing ssure and at the same time covering the ink-port 34.

In the forms of the invention already described it is to be observed that provision is made for cutting off the flow of the ink immediately at the rim of the opening to the interior of the holder at the pen-bearing end thereof. In other words, the cut off of ink is effected directly at the orifice where the ink comes from the nozzle to the pen-point, and in this particular the invention possesses decided and important advantages over analogous fountain-pen structures in which at-v tempts have been made to cut off the iiow of ink from the reservoir when the pen is not in use. It has been proposed in some types of pens to cut off the ink at a point back from the outer end of the nozzle; but where this is done a portion of the ink will remain within the nozzle or duct within the nozzle leading to the pen-point and, being cut off from the reservoir infront of the valve or equivalent cut-off, will ultimately run out into the cap if the point of the pen is carried downward or the case is shaken. The present invention is therefore designed as a special improvement upon pens, providing means for cutting off the ink from the reservoirin such a plane as to leave a quantity of ink in front of the cut-off or valve, inasmuch as the inl;- feeding device utilized in the carrying out of the present invention closes in or cuts off all of the ink bacl; of the pen-point, so that none whatever is left in the spaces or fissures in advance of the cut-oit or valve.

While the ink-feeding device already described accoinplishes the very important and advantageous results noted, still said device as a fixed feeder for the pen-point provides simple and effective means for flowing the ink to the pen with certainty and regularity, besides obviating bleeding or dropping of the ink from the pen-point, as is common in some types of fountain-pens. Hence the modification shown in Fig. 13 of the drawings may be resorted to. In this modification preciselythe same construction of feeder as shown in Figs. Sand 9 of the drawings may be employed, said feeder consisting of a substantially straight shank 40, extending into the reservoir and provided with an intermediate flattened portion 4l, lying Within the pen-bearing section. The said shank 40 is designed to be held station ary Within the nozzle and pen-bearing section by means of a fastening-pin 42, and the said shank 40 is also provided at its outer end with the terminal feed-head 43, having extended therefrom the feeding finger or bar 44, underlying the pen-point and provided therein with an airvent 45 in communication with the longitudinally-disposed air port or slot 46 in the shank contiguous to the head 43. The said head 43 is held spaced from the contiguous end of the pen-bearing section to provide an intervening ink-flowing fissure 47, which corresponds in location and function to the inkflowing fissure involved in all of the forms of the invention hereinbefore described.

Many other modifications might be resorted to in the carrying out of the invention-such, for instance, as shown in my companion application iiled of even date herewith, Serial No. 28,788--and it will be understood that various changes in the form, proportion, and minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this im vention.
